Management of urethral diverticulum complicating hypospadias repair.
BACKGROUND
Urethral diverticula can occur after hypospadias repair, and may lead to stone formation, incomplete voiding, infection, postvoid dribbling, haematuria and other problems. We previously reviewed our experience with hypospadias complications. We separately analyzed those patients who developed urethral diverticula to attempt to identify predisposing factors and appropriate management strategies.


METHODS
We reviewed the available medical records and charts of 123 patients undergoing re-operation for hypospadias complications at The Children's Mercy Hospital from 1 May 1984 until 1 January 2003. Hypospadias cripples, traumatic fistulae, complications after circumcision and true intersex patients were excluded.


RESULTS
Diverticula accounted for 11% of all complications (13 patients). The patients with diverticula were more likely to have perineal/proximal hypospadias. The initial repair was island tube urethroplasty in five, island onlay urethroplasty in seven and bladder mucosal graft in one child. The repair of the diverticulum in one stage was successful in 10 of the 13 patients. There was one recurrent diverticulum and two fistulas. A stricture was present in only one of the 13 patients but was detected overall in 14 of the 123 patients (11%).


CONCLUSIONS
Diverticula are uncommon after hypospadias repair, accounting for 11% of all complications in the present series. The stricture was not causative in 12 of 13 children. Repair of the diverticulum was successful after one attempt in 10 of 13 patients. The management of this complication is discussed.
